I thought I would play around and make some maps for Quakelive for any "future" competitions they may have and thought about converting an old map that I made for Quake 4 :D

However, GTK radient doesn't seem to be able to just open the map and I may need Quake 4 installed? Unfortunately my Quake 4 cd is back in SA, is there any way to just convert the geometry?

The map was 80% complete and I thought it was pretty good, so it would be nice to be able to use that rather than start from scratch.

Any ideas?
